Dear EEGLAB, <u></u><u></u></p><div><p class="MsoNormal"><u></u> <u></u></p></div><div><p class="MsoNormal"><u></u> <u></u></p></div><div><p class="MsoNormal">I have only a few electrode information from my subjects,as they had bandages on their head. I want to analyze FP1 and Fz. These electrodes are so close to eyes and therefore, prone to eye blinks. I am wondering if I can do the ICA analysis for eye blink rejection on only these two channels. If so, how can I detect the eye-blink related components, since I do not have their scalp maps. <u></u><u></u></p>
